Although printed for release in ''Bakugan: Evolutions'', Aura never saw release; it is the only unreleased Nanogan, and one of the few Reboot Bakugan molds that reached final printing that never saw release, alongside [[Neo Howlkor]], [[Neo Wrath]], [[Pegatrix x Goreene|Pegatrix x Goreene Core]] and [[Skullor]].
